ENDLESS CONVEYER.

Application filed May 16,

To aZZ whom it may concern.

Be it known that I, Lnwrs K. DAVIS, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Endless Conveyers, of which the following is a specification.

lhis invention relates to certain new and useful improvements in endless conveyors and it more particularly belongs to that class of conveyors which are used for the purpose of conveying reinforcing strips to a suitable backing, with which, in the process of manufacture said strips are incorporated to form a stiffened fabric. I

Reference is made in this connection to my application for a machine for. making stiffened fabrics filed on the 17th day of May,

1921, Serial No. 470,471.

lVith these and other objects in view which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention, may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

In order to make my invention more clear,- ly understood, I have shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

, In the drawings:

Figure 1 represents a plan view of two of the elements of a conveyer with a third one indicated in dotted lines, each of which is adapted to carry a lath or reinforcing strip. I

Fig. 2 is a side View of one of said elements. v

Fig. 3 is a bottom plan view ofthe two elements shown in Fig. 1, showing the strip receiving side of two adjacent elements.

Fig. 4C is an enlarged sectional View on the line 4-4: of Fig. 2 of one of said elements.

Fig. 5 is an enlarged detailed perspective View, showing in position, several of the link plates, one of which is mounted near each end of each element.

1921. Serial No. 470,059.

Fig. 6 is a detail View of one of the link plate rollers, and

Fig. 7 is a detail view of a link plate roller pin by means of which the roller is mounted in the link plates The numeral 1 represents a conveyer element consisting of a metallic bar of rectangular configuration having the upper side 2 plain as shown in Fig. 2. The lower side is provided with spaced transverse bars or plates 3, preferably made integral, recessed portions 4 and guide plates 4 adapted to fit therein and to be secured by screws to the bottom. Near each end of the element is a cut-away portion 5 as seen in F ig. Qand securely fastened therein by means of screws or bolts 6 is a link plateTprovided upon its upper side with apertures Sfor the reception of bolts 6 by which it is firmly united to the conveyer element, and, is provided on its sides with apertures 8. I

The bars 1 are provided on each end with a linkplate 7 and each link plate is loosely fastened or connected with the one preceding and the one following by the link plate roller pin 10, carrying the link plate roller.

9 which turns thereon. The pin 10 has a head 11 at one end and the other end is provided with an aperture 12 through which, when placed in position is inserted a cotter pin 13, as clearly seen in'Figs. 2 and 7.

Referring to Figure 5 itwill be observed that the respective link plates are positioned in staggered relation one to the other, this arrangement having been adopted so as to bring the plates close together. The arrangement is such that as the-conveyer passes over a sprocket wheel thereunder its teeth are adapted to fit between and against the sides of the respective link plate rollers and carry 7 the several elements forward. 7 V

The shape of the conveyor element is clearly shown in sectionhnes n Fig; 4 wherein is seen .oneach side a guiding plate l against which the strip lies and one of the transverse bars 3 upon which the lath or strip rests at spaced intervals, the purpose of which is to bear against-the bottom of the reinforcing strip and hold it against the pressure upon it as it passes through the machine.

The-guiding plates 4, may oe made separate from the element and attached thereto by rivets or any suitable means. The reason for this is because of the very considerable degree of wear to which they are subjected, and hence they may be made removable so that should one become worn it can be read ily replaced by a new one.

Vhile I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of illustration, asit is apparent that many modifications and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.

I claim as my invention:

1. In a device of the character described, a conveyer element comprising a longitudinal bar, a series of transverse bars across one face of the element, guide plates on each side therof and means near each end to engage a wheel thereunder and carry the element forward.

2. In a device of the character described, a conveyer element comprising a longi tudinal bar, integral transverse bars across one face of the element, guide plates on each side thereof and means near each end to engage a wheel thereunder and carry the element forward.

3. In a device of the character described, a conveyer element comprising a longitudinal bar, a series of'integral transverse bars across one face of the element, removable guide plates on each side thereof and means near each end to engage a wheel thereunder and carry the element forward.
